head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Practiced Mastery
Planning squad approaches to scripted missions where one mistake kills.

Optimization · Practiced Mastery
Precisely timing simultaneous character actions to execute optimal stealth routes through fixed guard patterns.
Hidden & Dangerous 2 leans Optimization (Practiced Mastery); Shadow Tactics: Blades of the Shogun leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden & Dangerous 2
Deliberate aim and stealth movement punish sloppy hands
Shadow Tactics: Blades of the Shogun
Precise timing windows on simultaneous multi-character abilities matter
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden & Dangerous 2
German AI follows patrol scripts, not adapting to you
Shadow Tactics: Blades of the Shogun
Guard patrol routes are fixed; no opponent models you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden & Dangerous 2
Patrol routes and enemy positions are unknown first attempt
Shadow Tactics: Blades of the Shogun
Guard cone randomness is minimal once patterns are learned
Shadow Tactics: Blades of the Shogun leans a little harder on optimization, though the gap is small.
Hidden & Dangerous 2
Squad planning, loadouts and approach routing decide missions
Shadow Tactics: Blades of the Shogun
Route planning and ability combo sequencing reduce to near-perfect solutions
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
